Source: Chelsea Clinton's Marriage Still Going Strong

Chelsea Clinton might not be with her husband right now, but she's still with him.

A source close to the couple assures E! News that the former first daughter's marriage to Marc Mezvinsky is not in trouble, contrary to rumors that Mezvinsky's recent jaunt to Jackson Hole, Wyo., without his wife meant they were splitting up.

The source says that Mezvinsky recently left his investment banking job at G3 Capital in NYC and is taking "time off" to go skiing.

The breakup reports, spearheaded by the National Enquirer, are "not true," the source says. "They're a very happy couple."

He and Clinton tied the knot just last summer in an incredibly private (yet well-attended) ceremony in Rhinebeck, N.Y. They met in Hilton Head, S.C., when they were teenagers and ended up attending Stanford at the same time, but they didn't hook up romantically until 2005.
